How to : 1) Create a new pywps process into your : PYWPS_PROCESSES directory 2) Copy and paste the code bellow into a new gml2png.py file 3) Define the process into your __init__.py __all__=["gml2png"] 4) Thats All... + Test if gml2png is on ProcessOfferings http://localhost/cgi-bin/wps?service=wps&request=GetCapabilities&version=1.0.0 + Execute the process http://localhost/cgi-bin/wps?version=1.0.0&service=wps&request=execute&identifier=<strong>gml2png</strong>&datainputs=[data=http://localhost/tmp/wgs84_vallecauca_v.gml]&responsedocument=[pngresult=@asreference=true] + wait for your ProcessSucceeded response .. and check for the generated file into your defined : outputPath accessed over outputUrl .. # GML2PNG # Author: Andres Herrera <t763rm3n gmail com> # For: PyWPS 3.0.0 from pywps.Process.Process import WPSProcess import os class Process(WPSProcess): def __init__(self): WPSProcess.__init__(self, identifier = "gml2png", version = "0.1", storeSupported = "true", statusSupported = "true", title="GML2PNG", abstract="Converts a GML Vector File to Raster PNG File", grassLocation = True) self.dataIn = self.addComplexInput(identifier="data", title="Input data", formats=[{"mimeType":"text/xml"}]) self.dataOutPNG = self.addComplexOutput(identifier="pngresult", title="PNG Result", formats=[{"mimeType":"image/png"}]) def execute(self): self.cmd("g.region -d") out=self.cmd("v.in.ogr dsn=%s output=data" %\ (self.getInputValue('data'))) self.cmd("g.region vect=data") os.system("export GRASS_TRANSPARENT=true") self.cmd("d.mon start=PNG",stdout=False) self.cmd("d.vect data") self.cmd("d.mon stop=PNG") self.dataOutPNG.setValue("map.png") References: PyWPS , OGC, OGC WPS
